RESUMEN

Portal vein thrombosis (PVT) worsens the long-term prognosis of patients with cirrhosis; however, the optimal treatment remains to be determined. Reports on the efficacy of direct oral anticoagulants are increasing, and further evidence is needed. Therefore, we investigated the effectiveness of treatment with edoxaban in patients with PVT. We retrospectively reviewed the outcomes of edoxaban and warfarin as antithrombotic therapies for PVT. The median overall survival time was 4.2 years in patients with PVT, with a 1-year survival rate of 70.7% and a 5-year survival rate of 47.9%. The leading cause of death was hepatocellular carcinoma. The overall response rate for thrombolysis in the edoxaban group was 76.7% compared to 29.4% in the warfarin group, and edoxaban significantly improved PVT compared to warfarin. In addition, edoxaban provided long-term improvement of PVT. Warfarin, on the other hand, was temporarily effective but did not provide long-term benefits. The Child-Pugh and albumin-bilirubin scores did not change after edoxaban or warfarin use. No deaths occurred due to adverse events associated with edoxaban or warfarin. Edoxaban as a single agent can achieve long-term recanalization without compromising the hepatic reserves. Edoxaban is easy to initiate, even in an outpatient setting, and could become a major therapeutic agent for the treatment of PVT.

RESUMEN

BACKGROUND: Hepatocellular carcinoma (HCC) in autoimmune hepatitis (AIH) was considered rare but is increasing with prolonged prognosis. Its impact on the overall prognosis of AIH is unknown, and treatment has not been established. AIM: To investigate the risk factors and prognosis of HCC in patients with AIH and identify appropriate management strategies. METHODS: We studied patients with AIH including background liver disease, sex, age, complications, treatment, response to treatment, liver fibrosis, prognosis, and treatment. RESULTS: In 131 patients, deaths due to liver failure were more common early after the onset of AIH; however, deaths due to HCC increased gradually. HCC was observed in 12 patients (median age, 70 years; male/female, 4/8; cirrhosis at onset, 11; median time to carcinogenesis, 7 years). Cirrhosis at diagnosis was identified as a risk factor for carcinogenesis in the multivariate analysis (odds ratio, 41.36; p < 0.0001) and cumulative cancer rates were high. Multidisciplinary therapy other than immune checkpoint inhibitors was administered as treatment for HCC. Two of the three patients who used molecular-targeted drugs discontinued the treatment because of adverse events. CONCLUSION: HCC is an important cause of death in patients with AIH. Currently available drug therapies are limited and early detection is desirable. TRIAL REGISTRATION: This trial was retrospectively registered in the Ethics Committee of Kagawa University School of Medicine under the identifier 2019 - 238, registered on 4 Feb 2020.

RESUMEN

PURPOSE: To test indocyanine green retention rate at 15 minutes (ICG-R15) as a prognostic biomarker in patients with hepatocellular carcinoma (HCC) treated with transcatheter arterial chemoembolization (TACE) therapy. MATERIALS AND METHODS: This retrospective cohort study was performed on the data of 278 consecutive patients with HCC treated with TACE after ICG-R15 testing at a single university hospital. Cox proportional hazard model analysis was performed to identify independent prognostic factors. After adjusting for age, sex, stage of HCC, albumin-bilirubin score, etiologies, and baseline year by propensity score matching, the prognostic impact of higher ICG-R15 was evaluated using the Kaplan-Meier curve. RESULTS: Univariate and multivariate analyses identified higher ICG-R15 as a positive prognostic factor for overall survival. Propensity score matching generated two 77-patient cohorts: ICG-R15 <20% group and ICG-R15 >20% group. The overall survival of the ICG-R15 >20% group was significantly better than that of the ICG-R15 <20% group. CONCLUSIONS: Higher ICG-R15 acted as a positive long-term prognostic factor in patients with HCC treated with TACE.

RESUMEN

AIM: Indications of drug therapies to elderly patients with hepatocellular carcinoma (HCC) should be carefully determined. The current study assessed the safety and efficacy of molecular targeted agents (MTAs) in the elderly patients with HCC, and identified factors associated with prognosis in a real-world clinical setting. METHODS: In a retrospective observational study, clinical data of patients with unresectable HCC treated with sorafenib or lenvatinib as first-line treatment at our hospital between 2011 and 2022, were investigated. Clinical parameters, therapeutic effects, adverse events (AEs), and prognosis were evaluated separately for the non-elderly (<75 years old) and elderly patients (≥75 years old). RESULTS: Overall, 111 patients were enrolled, including 59 non-elderly and 52 elderly patients. Compared to the non-elderly patients, the elderly patients had significantly lower skeletal muscle mass and a significantly lower percentage of patients in poor general condition with performance status 2 or higher, but there were no differences in parameters related to liver function or nutritional status. There were no significant differences in the incidence of severe AEs and therapeutic effects between the groups. No significant difference in progression-free survival was observed in the elderly and non-elderly patients; however, overall survival (OS) for sorafenib treatment was shorter in the elderly patients than in the non-elderly patients. Elderly patients consumed lower doses of both the drugs, and relative dose intensity (RDI) 4 weeks after treatment (4W-RDI) was associated with OS. Further, OS in the elderly patients was significantly longer in the subgroup with high 4W-RDI as compared to that in the subgroup with low 4W-RDI. CONCLUSIONS: MTAs can be safely administered to elderly patients with HCC. Furthermore, 4W-RDI is associated with longer OS. Maintaining RDI in the early phase is crucial in predicting the success of treatment with MTAs, especially in the elderly patients.

RESUMEN

Chronic hepatitis B (CHB) is a major global health concern. Guidelines for the management of hepatitis B virus (HBV) indicate that the loss of hepatitis B surface antigen (HBsAg) is a key endpoint of interest. The present study aimed to examine long-term changes in HBsAg levels in HBV-DNA-negative, hepatitis B e-antigen (HBeAg)-negative patients treated with peginterferon (Peg-IFN) α-2a and nucleos(t)ide analog (NA), and to examine the conditions that make them susceptible to HBsAg decline. A total of 17 patients with CHB treated with NA and Peg-IFN were observed for 96 weeks (48 weeks of Peg-IFN therapy and 48 weeks of post-treatment follow-up). In this study, responders were defined as those with a 50% or greater decrease in HBsAg levels from baseline at week 96. Beginning at week 16 of Peg-IFN therapy, there was a significant difference in the decrease in HBsAg levels from baseline between the responders and non-responders. In responders, HBsAg levels tended to be >60% lower 16 weeks after Peg-IFN initiation than before initiation. Age at the start of NA use and the duration of NA use before Peg-IFN treatment initiation were significant pretreatment factors associated with HBsAg response. In conclusion, Peg-IFN was revealed to be more effective in HBeAg-negative patients with CHB who started NA at a young age and have been on long-term treatment, particularly if the HBsAg levels decreased to less than 60% of the starting level at week 16 after starting Peg-IFN treatment.

RESUMEN

Although there have been advances in the prevention and diagnosis of hepatocellular carcinoma (HCC) in recent years, many HCC patients are still diagnosed with advanced stage. Systemic therapy is indicated for unresectable HCC (uHCC) with major vascular invasion and/or extrahepatic metastases, and the atezolizumab plus bevacizumab (atezo/bev) combination is currently recommended as first-line treatment for uHCC. Recently, sarcopenia-related factors, including decreased skeletal muscle index (SMI), have been reportedly associated with prognosis in uHCC patients treated with sorafenib or lenvatinib. There are few reports on muscle strength assessments, including grip strength (GS), despite their importance in accurate sarcopenia diagnosis, and furthermore, there is no evidence regarding atezo/bev therapy. In this study, we investigated whether sarcopenia affects the clinical outcome of atezo/bev therapy. This study included 64 uHCC patients on atezo/bev therapy and assessed their GS and SMI, and SMI was measured using bioelectrical impedance analysis (BIA). We diagnosed sarcopenia based on GS and BIA-SMI and compared the clinical outcomes in the sarcopenia and non-sarcopenia groups. Of these patients, 28 had sarcopenia, and 36 had non-sarcopenia. Adverse events (AEs) frequently occurred, and the albumin-bilirubin score significantly decreased after atezo/bev therapy in the sarcopenia group than in the non-sarcopenia group. The median progression-free survival was 4.7 (0.4-26.4) and 10.6 (1.1-24.5) months in the sarcopenia and non-sarcopenia groups, respectively. The median overall survival (OS) was 12.6 (1.4-27.7) months in the sarcopenia group and was not reached in the non-sarcopenia group, indicating a significant difference in the Kaplan-Meier survival curves for both groups (p < 0.01). In multivariate analysis, sarcopenia was significantly associated with OS. In conclusion, sarcopenia was significantly associated with poor clinical outcomes based on the occurrence of AEs and decreased liver function in uHCC patients on atezo/bev therapy. GS and SMI are important parameters for accurately diagnosing sarcopenia.

RESUMEN

Computed tomography (CT) is often used in the diagnosis of sarcopenia. In this study, we validated the assessment of sarcopenia by the psoas muscle volume using versatile software. The study involved a retrospective analysis of data from 190 patients with liver disease who underwent grip-strength testing and abdominal pelvic computed tomography. To assess sarcopenia, SYNAPSE 3D was used to obtain the skeletal muscle index, the psoas muscle index (PMI), and the simple method. We also used the recently proposed PMI cutoff values, for which the usefulness has been evaluated (O-PMI). The cutoff value of the psoas muscle volume index (PMVI) was determined using one of the diagnostic methods as the gold standard. All diagnostic methods showed that patients with sarcopenia had shorter survival, with O-PMI having the highest hazard ratio (HR) (HR, 6.12; 95% confidence interval [CI], 2.6-14.41; p < 0.001). Even when sarcopenia could not be diagnosed by O-PMI, low PMVI was associated with shorter survival (HR, 3.53; 95% CI, 1.34-9.32; p = 0.01). PMVI may be useful in the evaluation of sarcopenia, including the identification of poor overall survival in cases that cannot be diagnosed by O-PMI, which is considered more useful than PMI.

RESUMEN

Understanding the interface between microplastics and biological systems will provide new insights into the impacts of microplastics on living organisms. When microplastics enter the body, they are engulfed preferentially by phagocytes such as macrophages. However, it is not fully understood how phagocytes recognize microplastics and how microplastics impact phagocyte functions. In this study, we demonstrate that T cell immunoglobulin mucin 4 (Tim4), a macrophage receptor for phosphatidylserine (PtdSer) on apoptotic cells, binds polystyrene (PS) microparticles as well as multi-walled carbon nanotubes (MWCNTs) through the extracellular aromatic cluster, revealing a novel interface between microplastics and biological systems via aromatic-aromatic interactions. Genetic deletion of Tim4 demonstrated that Tim4 is involved in macrophage engulfment of PS microplastics as well as of MWCNTs. While Tim4-mediated engulfment of MWCNTs causes NLRP3-dependent IL-1ß secretion, that of PS microparticles does not. PS microparticles neither induce TNF-α, reactive oxygen species, nor nitric oxide production. These data indicate that PS microparticles are not inflammatory. The PtdSer-binding site of Tim4 contains an aromatic cluster that binds PS, and Tim4-mediated macrophage engulfment of apoptotic cells, a process called efferocytosis, was competitively blocked by PS microparticles. These data suggest that PS microplastics do not directly cause acute inflammation but perturb efferocytosis, raising concerns that chronic exposure to large amounts of PS microplastics may cause chronic inflammation leading to autoimmune diseases.

RESUMEN

Sarcopenia-related factors, including the skeletal muscle index (SMI), are reportedly associated with prognosis in patients with hepatocellular carcinoma (HCC) receiving various treatments. However, there is no evidence relating to hepatic arterial infusion chemotherapy (HAIC). In this study, we investigated whether a low SMI was associated with worse clinical outcomes of HAIC. Seventy patients with advanced HCC were included. Clinical outcomes were compared between the decreased SMI (n = 27) and non-decreased SMI (n = 43) groups, which were classified according to changes in the SMI after 3 weeks of treatment. In the prognostic analysis, patients in the decreased SMI group had significantly shorter progression-free and overall survival (OS) than those in the non-decreased SMI group. In addition, poor nutritional status and liver function were associated with an immediate decrease in the SMI after HAIC. The therapeutic effect was worse in the decreased SMI group than in the non-decreased SMI group, although the incidence of adverse events did not significantly differ. In multivariate analysis, a decreased SMI at 3 weeks after HAIC was identified as a significant independent factor associated with OS. A decreased SMI in patients with advanced HCC undergoing HAIC was associated with poor prognosis. It is effective to monitor the SMI to evaluate general conditions and predict clinical outcomes.

RESUMEN

BACKGROUND: This retrospective, multicenter study evaluated the effect of pemafibrate treatment on liver function and fibrosis by liver function tests (LFTs) and various fibrotic biomarkers including FibroScan in non-alcoholic fatty liver disease (NAFLD) with hypertriglyceridemia. METHODS: A total of 138 NAFLD patients treated with pemafibrate at three hospitals between September 2018 and April 2021 were included. To evaluate the effect of pemafibrate treatment, FibroScan-aspartate aminotransferase (FAST) score, a novel index of steatohepatitis that can be calculated based on the aspartate aminotransferase (AST) value, controlled attenuation parameter (CAP), and liver stiffness measurement (LSM) was used. RESULTS: Serum TG levels were significantly decreased 4 weeks after pemafibrate treatment (p = 0.003). The levels of AST (p = 0.038), alanine aminotransferase (ALT) (p = 0.003), and gamma-glutamyl transferase (GGT) (p = 0.047) also significantly diminished 12 weeks after pemafibrate administration compared to before administration (p < 0.05). However, serum HDL-cholesterol (p = 0.193), LDL-cholesterol (p = 0.967), and eGFR (p = 0.909) levels were not significantly altered 12 weeks after pemafibrate administration. In addition, the fibrosis biomarkers' Type IV collagen (p = 0.753) and FIB-4 index (p = 0.333) did not significantly differ, while Autotaxin (p = 0.006) and the AST-to-platelet ratio index (APRI) (p = 0.003) significantly decreased 48 weeks after pemafibrate administration. No significant reductions in LSM (p = 0.959) and CAP (p = 0.266) were detected using FibroScan 48 weeks after pemafibrate administration. FAST score was significantly improved (p = 0.0475). CONCLUSION: Pemafibrate improved LFTs, including fibrotic biomarkers and FAST score, due to the hepatic anti-inflammatory effect, suggesting that pemafibrate may prevent disease progression in NAFLD patients with hypertriglyceridemia.

RESUMEN

A patient with genotype 1b chronic hepatitis C virus who had been treated with pegylated interferon and ribavirin (RBV) was treated with glecaprevir/pibrentasvir (GLE/PIB) for 12 weeks. A sustained virological response at post-treatment week 12 (SVR12) was achieved, but relapse occurred approximately 31 weeks after the end of treatment. The patient had a history of allergy to RBV and was treated with ledipasvir/sofosbuvir (LDV/SOF), achieving SVR12 and remaining hepatitis C virus-negative until 24 weeks after the completion of treatment. LDV/SOF can thus be a secondary treatment for GLE/PIB.

RESUMEN

Lenvatinib is a tyrosine kinase receptor inhibitor used to treat unresectable hepatocellular carcinoma (HCC). In this study, we investigated the antitumor effects of Lenvatinib treatment on HCC cell lines. Proliferation was examined in four HCC cell lines (HuH-7, Hep3B, Li-7, and PLC/PRF/5) using Cell Counting Kit-8 assays. Xenograft mouse models were used to assess the effects of Lenvatinib in vivo. Cell cycle, western blotting, and microRNA (miRNA) expression analyses were performed to identify the antitumor inhibitory potential of Lenvatinib on HCC cells. Lenvatinib treatment suppressed proliferation of HuH-7 and Hep3B, but not Li-7 and PLC/PRF/5 cells and induced G0/G1 cell cycle arrest and cyclin D1 downregulation in Lenvatinib-sensitive cells. Lenvatinib treatment also reduced tumor growth in HuH-7 xenograft mouse models. miRNA microarrays revealed that Lenvatinib treatment altered the expression of miRNAs in HuH7 cells and exosomes. Our results demonstrated the therapeutic potential of Lenvatinib and provide molecular mechanistic insights into its antitumor effects for treating HCC.

RESUMEN

Non-alcoholic steatohepatitis (NASH) is a common chronic liver disease with no decisive treatment. The sodium glucose cotransporter 2 (SGLT2) inhibitor ipragliflozin was developed as a new oral hypoglycemic drug, which can improve NASH via an insulin-independent glucose-lowering effect by inhibiting glucose reabsorption in the renal proximal tubules. However, ipragliflozin appears to modulate steatosis or inflammation via different pathways. To elucidate the new mechanism of ipragliflozin for the treatment of NASH, we evaluated its effects in a NASH mouse model (STAM mice) with beta cell depletion, and compared the expression of microRNAs (miRNAs) in STAM mice treated with or without ipragliflozin (16.7 µg/day for 5 weeks). Ipragliflozin reduced aspartate transaminase and alanine aminotransferase levels, along with reduced hepatic steatosis, hepatocyte ballooning, lobular inflammation, and liver fibrosis. In addition, ipragliflozin upregulated mitochondrial transport-related and antioxidant defensive system-related genes in the liver. Among 2555 mouse miRNA probes, miR-19b-3p was commonly differentially expressed with ipragliflozin treatment for 5 weeks in both the liver and serum but in different directions, with a decrease in the liver and increase in the serum. Therefore, ipragliflozin can improve NASH development likely through the antioxidative stress pathway and by regulating miR-19b-3p.

RESUMEN

BACKGROUND/AIM: Drug resistance to molecular targeted agents, such as lenvatinib, is an important issue. The aim of this study was to explore the mechanism of lenvatinib resistance and to investigate potential drugs that may improve the treatment of lenvatinib-resistant (LR) hepatocellular carcinoma (HCC). MATERIALS AND METHODS: LR cells were developed by long-term culture under lenvatinib exposure. We analyzed the biological characteristics of LR cells in vitro, and investigated the antitumor effects and endogenous mechanisms of cisplatin in LR cells. RESULTS: The proliferative potential of LR cells was enhanced by activation of ERK signaling and changes in several miRNAs. Cisplatin inhibited cell proliferation of LR cells and induced G2/M cell cycle arrest. Furthermore, cisplatin triggered the DNA damage response, via the ATM/ATR-Chk1/Chk2 signaling pathway. CONCLUSION: Proliferation of LR cells was induced upon ERK signaling activation. Cisplatin exerted antitumor effects in LR cells and was involved in the regulation of miRNAs associated with drug resistance.

RESUMEN

Hepatocellular carcinoma (HCC) is the most common primary malignancy of the liver and is one of the leading causes of cancer-related deaths worldwide. Regorafenib, a multi-kinase inhibitor, is used as a second-line treatment for advanced HCC. Here, we aimed to investigate the mechanism of the antitumor effect of regorafenib on HCC and evaluate altered microRNA (miRNA) expression. Cell proliferation was examined in six HCC cell lines (HuH-7, HepG2, HLF, PLC/PRF/5, Hep3B, and Li-7) using the Cell Counting Kit-8 assay. Xenografted mouse models were used to assess the effects of regorafenib in vivo. Cell cycle analysis, western blotting analysis, and miRNA expression analysis were performed to identify the antitumor inhibitory potential of regorafenib on HCC cells. Regorafenib suppressed proliferation in HuH-7 cell and induced G0/G1 cell cycle arrest and cyclin D1 downregulation in regorafenib-sensitive cells. During miRNA analysis, miRNA molecules associated with the antitumor effect of regorafenib were found. Regorafenib suppresses cell proliferation and tumor growth in HCC by decreasing cyclin D1 via alterations in intracellular and exosomal miRNAs in HCC.

RESUMEN

Hepatocellular carcinoma (HCC) is one of the major causes of cancer-related deaths worldwide. Sorafenib has been used as a first-line systemic treatment for over a decade. However, resistance to sorafenib limits patient response and presents a major hurdle during HCC treatment. Lenvatinib has been approved as a first-line systemic treatment for advanced HCC and is the first agent to achieve non-inferiority against sorafenib. Therefore, in the present study, we evaluated the inhibition efficacy of lenvatinib in sorafenib-resistant HCC cells. Only a few studies have been conducted on this topic. Two human HCC cell lines, Huh-7 and Hep-3B, were used to establish sorafenib resistance, and in vitro and in vivo studies were employed. Lenvatinib suppressed sorafenib-resistant HCC cell proliferation mainly by inducing G1 cell cycle arrest through ERK signaling. Hep-3B sorafenib-resistant cells showed partial cross-resistance to lenvatinib, possibly due to the contribution of poor autophagic responsiveness. Overall, the findings suggest that the underlying mechanism of lenvatinib in overcoming sorafenib resistance in HCC involves FGFR4-ERK signaling. Lenvatinib may be a suitable second-line therapy for unresectable HCC patients who have developed sorafenib resistance and express FGFR4.

RESUMEN

EB-TACE has recently been performed because of its lower hepatotoxicity compared to cTACE in less advanced HCC. However, local recurrence at the tumor margins is often observed after DEB-TACE. cTACE involves filling the intratumoral sinusoids with lipiodol-containing anticancer drugs and accumulating in the drainage area, which is the first site of HCC recurrence. The aim of this study is to evaluate the therapeutic effect of DEB-TACE followed by cTACE in HCC patients. Between 2014 and 2020, 65 patients with Barcelona clinic liver cancer (BCLC) stage B (intermediate stage) of HCC were enrolled and divided into two groups: one group received DEB-TACE followed by cTACE (cTACE group) and the other group received only DEB-TACE (non-cTACE group). Sixty-five patients were medically followed. The median observation time was 14 ± 13.1 months after the first DEB-TACE and outcomes were analyzed for multiple factors. Results: The complete response rate was significantly higher in the cTACE group than in the non-TACE group. The analysis showed that the only factor that increased the CR rate in the cTACE group was the total tumor number (less than four). The OS rate of CR patients was higher than that of non-CR patients in the cTACE group. Adverse events in the cTACE group included severe thrombocytopenia but only in one of twenty-seven patients. Conclusions: The combined therapy with DEB-TACE followed by cTACE may be a new effective therapeutic strategy for the intermediate stage of HCC patients.

RESUMEN

Formulating sequential therapeutic strategies based on the pathological conditions of patients and by using molecular targeted agents (MTAs) and transcatheter arterial chemoembolization (TACE) is crucial for the treatment of unresectable advanced hepatocellular carcinoma (HCC). The current report presents the case of a patient with HCC involving a large intrahepatic primary tumor and lung metastases, and discusses treatment strategies for advanced HCC based on the current literature. Sequential therapy with MTAs was effective after TACE. Lenvatinib was effective for treating the metastases in the lungs and spleen. Only the progressing intrahepatic tumor was additionally treated with TACE. The patient has been alive for 3 years and continued lenvatinib treatment without HCC progression or decline in liver function. In conclusion, although multiple MTAs introduced into the clinic have been gradually replacing TACE, on-demand TACE in the multidisciplinary treatment of advanced HCC may be effective for intrahepatic hypervascular tumors resistant to MTAs, including lenvatinib. It may be possible to re-initiate lenvatinib treatment with good efficacy against distant metastatic lesions, thereby contributing to long-term survival.

RESUMEN

There are limited studies that have evaluated the long-term outcomes in patients with hepatocellular carcinoma (HCC) recurrence after direct-acting antiviral (DAA) treatment. In this retrospective study, we aimed to investigate the recurrence rates, recurrence factors, and prognosis of 130 patients who were treated with IFN-free DAA treatment after treatment for HCC. The median observation time was 41 ± 13.9 months after DAA treatment. The recurrence rates of HCC were 23.2%, 32.5%, 46.3%, and 59.4% at 6, 12, 24, and 36 months, respectively. A multivariate analysis showed that palliative treatment prior to DAA treatment (HR = 3.974, 95% CI 1.924-8.207, p = 0.0006) and alpha-fetoprotein at sustained virological response 12 (HR = 1.048, 95% CI 1.016-1.077, p = 0.0046) were associated with independent factors for HCC recurrence (HCC-R). The 12-, 24-, and 36-month overall survival rates were 97.6%, 94.0%, and 89.8%, respectively. The 12-, 24-, and 36-month survival rates of the non-recurrence and recurrence groups were 97.7%, 97.7%, and 94.1% and 97.6%, 92.3%, and 87.9%, respectively (p = 0.3404). The size of the main tumor lesion and the serological data were significantly improved at the time of HCC-R after DAA treatment. This study showed an improved prognosis regardless of recurrence rate, which suggests that DAA treatment in HCV patients should be considered.

RESUMEN

BACKGROUND: Peritoneal dialysis (PD) is essential for patients with end-stage renal disease. Peritoneal fibrosis (PF) is a complex inflammatory, fibrogenic process. No effective treatments are available to prevent these processes. Hepatocyte growth factor (HGF) possesses anti-inflammatory and anti-fibrotic properties. The aim of this study was to analyze whether HGF suppresses MGO-induced peritoneal inflammation and fibrosis in a mouse model. METHODS: PF was induced by intraperitoneal (IP) injections of MGO for 14 days. C57/BL/6 mice were divided into three groups: Sham group (only vehicle); Sham + MGO group (PF induced by MGO); and HGF + MGO group (PF mice treated with recombinant human-HGF). PF was assessed from tissue samples by Masson's trichrome staining. Inflammation and fibrosis-associated factors were assessed by immunohistochemistry and quantitative real-time PCR. RESULTS: MGO-injected mice showed significant thickening of the submesothelial compact zone with PF. Treatment with HGF significantly reduced PM thickness and suppressed the expression of collagen I and III and α-SMA. Expression of profibrotic and proinflammatory cytokines (TGF-ß, TNF-α, IL-1ß) was reduced by HGF treatment. The number of macrophages, and M1 and M2 macrophage-related markers, such as CD86, CD206, and CD163, was reduced in HGF + MGO mice. CONCLUSION: HGF attenuates MGO-induced PF in mice. Furthermore, HGF treatment reduces myofibroblast and macrophage infiltration, and attenuates the upregulated expression of proinflammatory and profibrotic genes in peritoneal tissues. HGF might be an effective approach to prevent the development of PF in patients undergoing PD.
